[clang][SPIRV] Add builtin for OpGenericCastToPtrExplicit and its SPIR-V friendly binding (#137805) The patch introduce __builtin_spirv_generic_cast_to_ptr_explicit which is lowered to the llvm.spv.generic.cast.to.ptr.explicit intrinsic. The SPIR-V builtins are now split into 3 differents file: BuiltinsSPIRVCore.td, BuiltinsSPIRVVK.td for Vulkan specific builtins, BuiltinsSPIRVCL.td for OpenCL specific builtins and BuiltinsSPIRVCommon.td for common ones. The patch also introduces a new header defining its SPIR-V friendly equivalent (__spirv_GenericCastToPtrExplicit_ToGlobal, __spirv_GenericCastToPtrExplicit_ToLocal and __spirv_GenericCastToPtrExplicit_ToPrivate). The functions are declared as aliases to the new builtin allowing C-like languages to have a definition to rely on as well as gaining proper front-end diagnostics. The motivation for the header is to provide a stable binding for applications or library (such as SYCL) and allows non SPIR-V targets to provide an implementation (via libclc or similar to how it is done for gpuintrin.h).

Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is on the Clang forums:
